Is it permissible to eat soy products that look like non-kosher food, such as fake pepperoni? Is it permissible to eat cheese on a veggie burger or faux meat (soy) with cheese?
Soy is pareve (neither meat, nor dairy) and can be used to create food items that resemble non-kosher products in both sight and taste. Some kosher observers are uncomfortable eating a piece of pizza that has pepperoni-looking soy as a topping. Similarly, some find it distasteful to put cheese on a veggie (soy) burger or fake cheese on real meat. Further, some believe that this is a case of ma’arit ayin (appearance of impropriety), as the casual observer may suspect these dishes are not kosher. Others find this to be innovative and are comfortable with it. Several years ago, when margarine was introduced to the marketplace, many kosher observant Jews would only put it on the table when a meat meal was being served if it was wrapped in its packaging displaying the label, lest anyone think it was butter. Ultimately, this is a matter of taste. One should contact his/her rabbinic authority if there is concern about personal practice.
